CASEMENT WINDOW.

Application filed May 2,

To all whom it may concern:

Be it known that we, JOHN POLACHEK, JULIUS JEPsEN, and EDMUND PEREMI, citiens of the United States, and residents,

respectively, of the city of New York, borough of Manhattan, in the county and State of New York, of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, and of the city of 1 New York, Elmhurst Manor, Long Island, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Casement Window, of which the following is a full, clear, and exact description.

This invention relates to improvements in window constructions and has particular reference to a basement window.

An object of the invention is to provide the window frame and sash are so constructed that the same cooperate, when the window is closed, to effectively prevent the ingress of moisture and air into the interior of a room.

Another object is the provision of an improved window in which the frame and sash are contacted with each other at a plurality of points to form laterally arranged air chambers or pockets. A further object is to provide a metallic window construction, the parts of which may be readily assembled before delivery to .a building in which the window is to'be installed. i

The above and other objects will appear more clearly from the following detail description, when taken in connection with the accompanying drawings, which illustrate a preferred embodiment of the inventive idea.

In the drawings Figure 1 is a front elevation of the window constructed in accordance with the invention;

Figure 2 is a transverse section on the line 22 of Figure 1; I

Figure 3 is a vertical transverse section on the line 3-3 of Figure 1; and

Figure 4 is a perspective view of one of the stiles forming a portion of the window 50 sash..

In the construction of the window embodied in the present invention, the frame 1923; Serial No. 636,157.

and sash thereof may be made of steel, bronze, or other desirable material which is extruded to secure the desired formation of the parts. The window frame, which is generally indicated by' the numeral 5, includes the two vertical side sections 7, the top section 8 and the sill section 9, all of which are bent into substantially channel shaped formation, as best illustrated in Figures 2 and 3. The side section 6 and the top section 8 are of the same configuration, the former including the outer portion 10, the intermediate portion '11 and inner portion 12, which correspond to the outer, intermediate and inner portions 13, 1 1 and 15 of the top section 8. The sill section includes the outer portion 16, the intermediate portion 17 and the inner portion 18, while the'other side section 7 includes the outer portion 19, intermediate portion 20 and the inner portion 21. The outer portions 10, 13 and 19 of the sections 6, 8 and 7 v are formed with the channel members 22 which cooperate with the wall of the building to provide openings for receiving a suitable plastic material 23- utilized in anchoring the frame in position. The inner portions 12, 15 and 21 of the side and top sections of the frame are also formed so that the same may be suitably embedded in the wall forming the window opening. The channel formation of the sill section 9 permits of the introduction of suitable material 24 beneath said sill section to further anchor the frame in position. The side section 6, top section 8 and sill section 9 have their outer, intermediate and inner portions, respectively, provided with spaced flanges 25, 26 and 27, which are of successively decreasing widths so that the three edges thereof will project inwardly and be disposed in different planes for a purpose which will appear in the courseof the description. The other side section 7 of the frame is provided with only the outer and inner flanges 28 and 29 arranged in the same vertical plane with the flanges 25 and 26, the flange 28. being slightly greater in width than the flange 29.

The window, generally designated by the numeral 30, comprises the sash including the vertical stiles 31, 32 and 33, the latter two 6and Wlll presently appear, and the top and bottom rails 34 and 35, respectively. The stile 31 and the rails 34 and 35 are provided with spaced flanges 36, 37 and 38 of successively increasing widths which project outwardly and overlap, respectively, the flanges 25, 26 and 27, when the window is in closing po sition, so as to provide a plurality of points of contact between the sash and the frame. The stile 31 is provided with the flanges 39 and 40 which overlap and contact the flanges 28 and 29, respectively, while the stile 33 carried by the stile 32 is provided with a flange 41, which contacts the intermediate portion 20 of the section 7 of the frame, thus forming a third point of contact of the sash with the section 7. Interposed between the portion 20 and stile 33 is a suitable hinge 42 which pivotally connects the window sash with the section 7 of the frame, so that the window may be swung to opened and closed positions, this movement of the window being permitted by reason of the different widths of the various flanges and their relation with respect to each other.

When the window is in closed position the flanges 25, 26, 27 and 36, 37, 38combine, in conjunction with adjacent portions of the frame and sash, to form the outer and inner air chambers or pockets 43 and 44 which extend about three sides of the sash. The flanges 28, 29 and 39, 40 together with portions of the stiles 32 and 33 and the section 7 of the frame, form the outer and inner air chambers 45 and 46 which communicate at their ends with the chambers 43 and 44, respectively, thus providing two annular chambers about the sash. These chambers act as air cushions to effectively prevent air from entering the interior of a room between the various overlapping and contacting flanges, it being obvious that any air entering into the outer chambers 43 and 45 must also pass into the chambers 44 and 46, which are preferably of larger area than the outer chambers, and, from thence past the innermost flanges before entering the room.

The bottom rail 35 of the sash is provided along its outer edge with a downwardly curved flange 47, which overhangs the outer flange 25 and thus aids in preventing the ingress of moisture into the outer chamber 43 between the flanges 25 and 36. However, in order to insure against a collection of moisture in the chamber 43 the flange 25 may be provided with one or more drain openings 48 which will permit of any moisture within the chamber draining outwardly onto the outer inclined portion 16 of the sill section 9. Any suitable locking device, such as that conventionally shown at 49, may be employed for securing the window in its closing position.

What is claimed is:

In a casement window, a metallic frame including side, top and sill sections, each having an outer, intermediate and inner flange arranged at spaced relation and a window sash pivotally connected to one of said side sections and having outer, intermediate and inner flanges overlapping and contacting respectively the outer, intermediate and inner flanges of said sections, said side sections each having a substantially L shaped flange adapted to engage, a wall on one vertical edge, and an encircling flange structure on the opposite edge, said encircling flange structure being positioned to partly encircle a projection from a wall for anchoring the frame in place.
